I apologize for any confusion, but I'm not sure I understand your question correctly. Are you referring to replacing the bumper of a Holden Commodore VF1 with a bumper from an electric bicycle (e-bike)?
If that's the case, it's important to note that the bumpers of vehicles and e-bikes are not interchangeable. They are designed for completely different purposes and have different sizes, mounting points, and structural requirements. Vehicle bumpers are engineered to meet safety regulations, withstand impacts, and protect the vehicle's occupants in the event of a collision.
